Even if it had been 2017 / above model, again, duty would have been very high, and might have caused you an arm and leg here.
My brotherly suggestion:
Sale that car in Australia. I hope, you will be able to get a good price IN SHA ALLAH.
Come to Pakistan, and buy a brand new car here; any make, model, variant, etc. which matches your budget and requirements.
Experts can guide you here according to your budget and requirements.
I hope, this all helps. Thank you.
